How do I undo a "read only" in a microsoft word document?

Question

I was editing my word document so I could send it to my professor. When I tried to save it it said I was in "lock edit".
I have no idea how that happened. Then when I tried to save the document before sending it to the prof it said it was read only.

Answer 1

save it as a different document and at the save as site uncheck the box that says lock edit

Answer 2

Right click on the file, select properties and uncheck read only

Answer 3

Go to the file and right click on it then click properties then uncheck read-only then click ok and that should do it
